Answer:

5/6

Step-by-step explanation:

When dividing fractions, we use a rule where we keep the first number, change the sign, and flip the second number.

3 1/3 must be converted to an improper fraction before we can do this, though.

3 1/3 is 10/3 because we multiply 3 by the denominator, also 3, and then add one, so 10/3.

Now we can divide. Remember 4 is the same thing as 4/1

10/3 ÷ 4/1

Keep the first fraction the same, change the division sign into a multiplication sign, and divide by flip the second fraction.

It ends up looking like 10/3 x 1/4

Multiply: 10 x 1 and 3 x 4

It's 10/12, but we can simplify that by dividing both the top and the bottom by 2.

The final answer is 5/6

A and B are supplementary angles. If A = (5x + 27)° and B = (5x – 7)º, then find the measure of angle A.​
vazorg [7]

Answer:

x=16

(5x + 27)° =5(16)+27=80+27=107

(5x – 7)º= 5(16)-7=80-7=73

Step-by-step explanation

supplementary angle=180

(5x + 27)° +  (5x – 7)º=180

5x+27+5x-7=180

10x+20=180

10x=180-20

10x=160

x=160/10

x=16

(5x + 27)° =5(16)+27=80+27=107

(5x – 7)º= 5(16)-7=80-7=73

107+73=180

In a company, 37% of 1500 employees are females.work out the number of males in the company.
a_sh-v [17]
Formula:

y = p\% \times x
p = 37\% \div 100 = 0.37
y = 0.37 \times 1500 = 555
so there are 555 woman working.
1500 - 555 = 945
there are 945 men working

Find the constant of proportionality and unit rate for the data in the table. Then write the equation to represent the relations
Hatshy [7]

You should set up an X and Y table. Make time X and Distance Y. (the table is like a cross: on the left top put x and left top put y. Then under the line list the x and y numbers given in order.) Then find the "slope" which is y/x  (rise over run) then you get the increase rate of 45 mph. The relation between them would be D=45t
